Specific Information

Euphorbia coerulescens is a medium-sized shrub with a number of upright branches that join at a single short stem, close to the ground. The stems are longitudinally ridged with four to six angles and paired thorns along the margins. Each branch is further constricted into segments of 4 - 8 cm long, reportedly reflecting periods of rapid and minimal growth. The stems are usually unbranched except at the tip. The leaves are very small, scale-like and are only found on young growth for a brief period. This plant spreads by rhizomes into large colonies of tightly packed branches. Euphorbia coerulescens can withstand temperatures down to -12º C.

As with most Euphorbias the milky latex can irritate the skin and produces a burning sensation in the throat if swallowed. The latex can irritate the eyes and can cause blindness. If you come in contact with the sap, wash hands with soap and water, taking care to not touch face or eyes.

Distribution and Habitat

in the Western Cape in the Calitzdorp area in the Little Karoo, and in the Eastern Cape, in arid Karoo habitat in the Jansenville area, also known as the Noorsveld

Planting Suggestions

Euphorbia coerulescens is ideal for rock gardens and slopes with good drainage. Plant in full sun or in a position that gets just a little shade. In semi-desert conditions, these plants should be protected from the hottest afternoon sun. Do not over water. This Euphorbia​ spreads from underground stems.

If signs of rotting occur, cut off all rotten sections and dry out the rest of the branch until all cuts have healed and there is no sign of rot. This section can then be rooted in coarse sand.

Medicinal Uses

​Although Euphorbia coerulescens is not normally browsed by stock, it is used as supplementary fodder in times of drought, when it is cut into sections and left to wilt for a few days.
